more nitrogen use efficiency in crops is important for maintaining and developing sustainable agriculture. in order to study the effect of different levels of mushroom compost and different resource of nitrogen on yield, yield attributes and nitrogen use efficiency of wheat (triticum aestivum l.), an experiment was conducted at faculty of agriculture, ferdowsi university of mashhad, iran, durin...

A Global Framework for Best Management Practices for Fertilizer Use IPNI Fertilizer BMP and Nutrient Use Efficiency Working Group: Dr. Tom Bruulsema (Chair), Northeast North America Director Dr. Fang Chen, Southeast China Deputy Director Dr. Fernando García, Latin America Southern Cone Director Dr. Svetlana Ivanova, Eastern Europe and Central Asia Group Coordinator Dr. Shutian Li, Northwes...

Efficient nitrogen (N) fertilizer applications in onion (Allium cepa L.) can reduce input costs and improve fertilizer-use efficiency, while maintaining high yields quality. Understanding the N requirements of at different growth stages is necessary to enhance N-use efficiency (FNUE). In a two-year study (2021 2022), FNUE onions was determined five development (at transplant, vegetative growth,...

low nitrogen (n) use efficiency is considered to be one of the major problems in wheat production fields all over the world. this experiment was conducted to evaluate the effects of nitrification inhibitor (ni) 3, 4- dimethylpyrazole phosphate (dmpp) on the yield and nitrogen use efficiency of spring wheat (triticum aestivum l.) cv. bahar during 2011 at shahrekord university. a factorial experi...

The efficient management of nitrogen (N) fertilizer and irrigation is of utmost importance because they are two of the greatest expenses for corn production. This project was conducted to determine if yield and efficiency of fertilizer N in corn could be improved by applying N at later developmental stages through a subsurface drip irrigation (SDI) system. Experiments in 2014 and 2015 compared ...

Nitrogen management practices have an effect on crop yields but they can also have a negative impact on the environment. Practices such as banding fertilizer and/or split-applying total nitrogen needs per acre offer a more efficient use of nitrogen by significantly reducing nitrate leaching potential. Heavy rains occurring when plants are small and nitrogen demands are low can also increase nit...

There is increasing concern about the sustainability and environmental impacts of mineral fertilizer use in agriculture. Increased recycling of nutrients via the use of animal and green manures and fertilizers made from domestic organic waste may reduce reliance on mineral fertilizers. However, the relative availability of nutrients (especially nitrogen) is lower in organic compared to mineral ...

In newly planted orchards, special attention must be paid to fertilization to build up the permanent structure of the trees so that high yield and fruit quality can be reached later on. Nitrogen (N) plays a major role in the fertilization plan, although few studies have assessed its use efficiency in young nonbearing trees, especially in field conditions. In this work, 1–3 years old ‘Rocha’ pea...
